Did you ever manage to resolve this? I am having the exact same problem with the exact same router and mac mail dropping out intermittently. Any solutions would be greatly appreciated.

I tend to leave my computer on 24/7 and found that the problem only occurred when the hard drive on my Mac came out of sleep mode.
I have therefore set the drive to never turn off. An unsatisfactory solution, I feel, but it worked.
My previous router was a Telkom ADSL 5102G. I didn't realise it at the time but there was a similar problem with that one also. I would come back to my computer, touch a key, bring the hard drive out of sleep mode, and I always had a display - only for a few seconds - that I had no internet connection. It would then immediately resolve itself so I never worried about it.
I hope that one day, Apple and the router manufacturers get together to resolve this. The fact that I never had either of these issues when running Windows and Microsoft Outlook, even when I had the Mac and a Windows computer connected to the same router at the same time, implies to me that the problem lies somewhere with Apple.

I found a solution. It appears to be a DNS problem. Go to System Preferences>Network>Advanced then click on the DNS tab. Under DNS Servers delete your routers address and type in the Google Public DNS 188.8.131.52 and 184.108.40.206. Restart mail and it doesn't lose connection again. It worked for both my macbooks.
I'm no techy, but I assume this is just some sort of work-around that keeps the communication between the router and computer open. I read about it over a number of pages listed here (https://discussions.apple.com/thread/4268728?start=90&tstart=0). While some suggest it is slightly inefficient, there hasn't been any noticeable change in my download speeds.
Hope that helps.

I switched over on receipt of your post and it has worked fine since. I was also intrigued as to why my first post did not pick up the thread that you sent. The problem seems to have been around for a long time and many people mention that Apple should provide a fix.
I am glad that I can now put the computer to sleep.

I set my hard drive to go into sleep mode after 20 minutes.
If I leave Mail running whilst I am away, when I return the connection doctor is displaying the same error on both my Gmail and Telkomsa accounts.
However, if I give it a few seconds for the hard drive to come fully out of sleep mode and I then click to check for mail, connection is made to the mail servers.
Clearly this is not the ideal situation but I will stick with it rather than keep the hard drive on permanently.

Yeah, it's clearly not a perfect solution. The problem came back for me yesterday. I just couldn't be bothered anymore so I boxed it up and put it in the cupboard and plugged in my old router. Everything is back to normal so far, althought I am significantly out of pocket - what a waste of money.
